Abstract
INTRODUCTION: The aim of this work is to evaluate treatment persistence and clinical outcomes after 6 months of on-label guselkumab use in patients with rheumatologist-diagnosed active psoriatic arthritis (PsA) enrolled in the CorEvitas PsA/Spondyloarthritis Registry. METHODS: Participants with PsA who initiated and persisted with on-label guselkumab use post-Food and Drug Administration (FDA) approval for active PsA (7/13/2020; subcutaneous 100 mg at weeks 0, 4, and every 8 weeks) at their 6-month follow-up visit (occurring through 3/31/2023) comprised the primary analysis population (On-Label Persisters). Hierarchical, multiplicity-controlled primary and secondary outcomes were mean (95% confidence interval) changes from baseline at 6 months in clinical Disease Activity Index for PsA (cDAPSA; primary), Physician Global Assessment (PGA) of arthritis and psoriasis (visual analog scale [VAS] 0-100), patient-reported pain (VAS 0-100), and percent body surface area with psoriasis (%BSA). Paired t tests determined changes that were statistically significantly different from 0 (α = 0.05). RESULTS: Among 114 patients who initiated on-label guselkumab and had eligible baseline and 6-month visits, 90 (78.9%) had persistent use. Among these On-Label Persisters at baseline, mean duration of PsA symptoms = 13.6 years; mean cDAPSA, PGA, and patient-reported pain = 22.0, 42.3, and 57.0, respectively; 94.4% had a history of psoriasis (mean BSA 7.6%); and 18.9% and 73.3%, respectively, previously received 1 or ≥ 2 biologic/targeted synthetic disease-modifying antirheumatic drugs. The mean change (improvement) in cDAPSA was - 5.4 (- 8.5, - 2.3; p < 0.001) at 6 months. Significant mean improvements in PGA (- 19.0 [- 24.2, - 13.8]), patient-reported pain (- 9.1 [- 14.4, - 3.8]), and %BSA (- 5.1 [- 7.6, - 2.7]) were also observed (all p < 0.001). CONCLUSIONS: In this real-world PsA population, generally characterized by longstanding, treatment-resistant, active disease at baseline, persistent guselkumab use in nearly 80% of patients with on-label use was accompanied by significant improvements in joint and skin symptoms and patient-reported pain at 6 months. These registry data support results from randomized clinical trials demonstrating the efficacy of guselkumab in improving PsA signs and symptoms. TRIAL REGISTRATION: clinicaltrials.gov: NCT02530268.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
